3GPP2 Air Interface Perspectives TSG-C Structure & Activities Dr. Edward Tiedemann (Qualcomm) Chair, 3GPP2 TSG-C 1 6 November 2009

2 TSG Radio Access (TSG-C) is responsible for the radio access part, including its internal structure, of systems based on 3GPP2 specifications. TSG-C Responsibility More specifically, TSG-C is responsible for the cdma2000 air interface and many services. TSG-C has developed 87 specifications, 17 reports, and numerous revisions. 2
